@With reference more in detail to the draw ings,:it will be seen that our improved ma chine comprises an elongated table of frame construction and designatedgenerallyby the reference character T; This table'comprises supporting legs 5 secured at their upper ends to spaced'par'allel longitudinal side frame members 6 6. a V

The side frame members '6 of the table at their rear ends are-connected by a cross mem ber 7 so that the table is substantially U -shaped in cross section. I

Extending transversely across the table T intermediate the'ends'of the table, are a air of spaced parallel. track supporting ars 8 -8. As shownto advantage in Figure 2 these track supporting bars-8 extend laterally from opposite sides of the table, the bars extending for agreater distance on one side struction, and the rails 10 of the lower guide tracks at their outer or entrance ends are curved upwardly and forwardly as at 11 to merge into the upper rails 9 inwardly from the forward end of the rails as also shown to advantage in Figure 2.

Supported on that portion of the bars 8-8 resting on the table T is a housing designated generally by the reference character H. This housing H comprises a bottom wall 12, a side wall 13, and a top wall 14. The housing is further divided into an upper compartment 15 and a lower compartment 16 at the rear end thereof through the medium of a horizontally disposed partition 17.

At their forward ends, the tracks 9 and 10 extend through the open. side of the housing and into the housing to terminate at the rear wall of said housing. The ends of the upper tracks rest on the partition 17. The forward end of the lower track 10 rests upon the bottom wall of the housing. A pair of brace members 1818 are arranged on one side of the track structure F and disposed one to each side of the table T, said brace members 18 at their upper ends converging toward one another to fit against the adjacent sides of the housing H, extending above the top of the housing.

At their upper ends, these brace members 18 are connected by cross brace rods 19.

These brace members 1818 being arranged in pairs, one pair to each side of said track structure provides a suitable framework for retaining the housing H in position.

At its forward end, and to one side of the frame structure F the housing H has a side wall section 13, thus cooperating the adjacent portion of the top wall 14, bottom wall 12 and the other first mentioned side wall 13 a substantially rectangular shaped structure constituting what may be termed a form or container holder designated generally by the reference character C. Over this portion of the housing designated as the container holder C may be slid a carboard container, wooden box, or other similar receptacle as shown in dotted lines in Figure 3 so that the receptacle opens into the housing for a purpose to be hereinafter more fully set forth.

Suitable braces 21 may be employed for bracing the guide frame structure. F and retaining the same in position upon the horizontal support bars 8.

As shown to advantage in Figure 3, the box holder or form C projects over a raised. platform mounted. on the forward end of the table and designated generally by the reference character P. The raised platform P may be of any suitable construction, but preferably is shown comprising a plurality of transverse bars 23 secured at their opposite ends to the frame members 6 and longitudinal bars 24 preferably in the nature of elongated strips of metal resting upon and intersecting the bars 23, so that the platform P is in the nature of a grid.

The platform P may be utilized for resting the filled containers thereon after the latter have been removed from the form C.

Track rails 24-.24t are disposed flush with the bottom 12 of the housing and extend from the opposite end of the housing, said rails at their opposite ends being supported on a cross bar 25. These rails 24 provide a trackway for a pusher carriage designated generally by the reference character B. This pusher carriage R is of the structure best shown to advantage in Figures 1 and 3 and comprises spaced parallel bottom frame bars 25 connected at their forward ends through the meoium of a cross bar 26 and a pair of upper frame bars 27 connected at their forward ends through the medium of a cross bar 28.

The upper frame bars 27 have downwardly and rearwardly curved end portions 29 converging toward one another at their ends and are bolted to the rear end of a brace member 30 extending rearwardly from the intermediate portion of a cross brace member 31 connecting the rear ends of the lower frame members 25. Side brace members 32 are secured at their upper and lower ends to the upper and lower frame bars 27 and 25 respectively.

Supporting rollers 33 are mounted at the forward ends of the lower frame bars 25 and ride upon the track rails 24. Thus it will be seen from a study of Figure 3 that by moving the pusher carriage along its trackway to the left of Figure 3, the carriage will enter the housing H, the upper bars 27 extending into the housing and positioned within the compartment 15 and the lower frame bars 25 into the compartment 16.

The upper and lower cross frame bars 28 and 26 respectively at one end have suitably mounted thereon anti-friction rollers 34: as at 35 to engage with the inner face of the side wall 13. At their opposite ends, each of the said members 28 and 26 respectively are pro vided with upper and lower can engaging rollers 36 as also shown to advantage in Figure 2.

To permit the passage of the pusher carriage R through the housing H, the lower track rails lO lO are suitably notched as at 1010 to permit the supporting wheels 33 to passthcrethrough as also shown to advantage in Figure 2.

Between the rear end legs 5 of the table, and adjacent the lower ends thereof there is disposed a horizontal shaft 37. The ends of the shaft being secured in the said end legs 5. An elongated operating lever 38 has one end pivotally mounted on said shaft and this lever 38 inclines upwardly and forwardly to tracks and into the housingiH- xten b yea jthe e i s nt t rwa snd i t teb ess a is; d a ag s F 3- Th le e 3 i i ermel y ld in h s p sition t rough the m d um f. a. oilspripg .one endlof which may be anchored to one of theme u po i 7 and i otherfendsecured tothellever 38 adjacent the pivoted endofthe latter. A connecting rod 410 has one end thereof pivoted on the shaft 37 adjacent the pivoted end of the lever 38, and at its upper end the rod-e0 is pivoted as at 11 to the rear end of the pusher carriage frame memberBO. The lever 38 is connected to the operating rod a0 ,through the medium olf a link 42, the ends of which ,link are pivoted to I jacent end portions of the lever and connecting rod respectively.

Manifestly, when, the lever 38 s in that pos tion shown i Figured, being held the emu der the action of the coil spring 39, the pusher carriage R will be disposed outwardly of the housing H vor in that position also Shown Eigure 3'. .Whenpressure 1s applied-tothefree endof the lever 38 for rockin gthe same, the bar 40 will be rocked upon llQSjPlVOhtO move towards the left in Figure 3,

It is believed that from theforegoing dew scription, taken in connection with the acm yins' d awi a clear d s anding of the operation, construction, utility and advantages of a packing machine of this c aracterwill be had Withoutamore detai ed de ription.

igure 1.0 we have shown a modified form of can engagingroller, and as therein illustrated-it will be seen that the roller. is designated generally the reference character 36a, and that the Same is disposed in avertical position'being journalled between the co-extensive arms of a .U shaped bracket L mounted on the ends of the cross bars 26 and 28 respectively in lieu of the rollers 26 for engaging the cans for-the same purpose as the said rollers 26: I

I i-Figure l1 we have shown a still further modification- 0f these can engaging rollers, and as thereinillustratedthe can engaging roller designated by the reference character 36?) and is to be mounted in say-shaped braclget in the same manner as the can engaging roller 36o, However, it will .be noted that the can engaging roller 36a tapers inwardly from its opposite ends and conforms somewhatto the contourof the ean which it engages, .while in the last instance,= that is, the roller 36?) may be ofuniform diameter throughout its entine length. However, either of these forms will be found to be W adap o h purpos d s ned and described, and the scope, of the appended claims. 7 Having is claimed as'new is: 1
